Abstract: A vehicle front body structure is provided for reliably transferring a collision load to a crash can and a front frame by preventing a bumper beam from buckling during a small overlap collision. Bending rigidity of the bumper beam in a vehicle width direction is such that 1) a bending moment generated on the bumper beam when a collision load in a direction toward a vehicle rear side is applied to an extending section, which extends outward in the vehicle width direction from a crash can fixed section, is the highest in a vehicle width direction inner end portion of the crash can fixed section on a side where the collision load is applied, and 2) the bending moment is continuously reduced as a distance from the vehicle width direction inner end portion in the vehicle width direction increases.

Abstract: A front vehicle-body structure is provided that is lightweight and reduces an impact load transmitted to lower limbs of an occupant. Embodiments include a transmission disposed in a vehicle front portion, a dash lower panel dividing an inside from an outside of a vehicle cabin in a vehicle rear of the transmission, and an organ type accelerator pedal disposed on a vehicle-width-direction inner side of the dash lower panel opposed to the transmission. The dash lower panel includes a panel rear portion in which the accelerator pedal is arranged, a panel front portion extending from the panel rear portion to a vehicle front upper side, and a fragile portion extending in a vehicle width direction along a boundary between the panel rear portion and the panel front portion, which is fragile compared to the panel rear portion and the panel front portion.
